Hi TerricaPinder. Welcome to Thrive Forums! If you need instructions for wiping the cache from recovery here's how to do it. (don't panic if you see a dead looking android guy. That's normal)
Press and hold the volume+ button down.While continuing to hold volume+, press and hold the power button until you feel the vibration. Let go of the buttons.

You will use the volume rocker to scroll/navigate through the options, and the power button to select them.
